Write a function called pluck, which takes an array of objects and the name of a key. The function should return an array containing the value associated with that key for each object, or undefined if that key is not present in the object. code example

Example: Getting One Value from an Array of Items

//Getting One Value from an Array of Items or sum of array
var numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];
var total = numbers.reduce(function(total, current) {
    return total + current;
}, 0);

console.log(total);
